In most instances, this sexual activity involves the man placing his penis between his partner's breasts. He then thrusts while the breasts are squeezed around the penis for more excitement. Mammary intercourse is sometimes combined with oral sex (blowjob).

Sometimes mammary intercourse continues to the point of ejaculation. The semen can land on the breasts, face, or in the mouth of the partner. A great many gay male chubby chasers enjoy their partners' breasts. They may engage in male-male breast frottage if the breasts are large enough.

Several slang terms refer to mammary intercourse. These slang terms include titfuck or titty fuck in the United States. Tit wank or French fuck are slang terms used in the United Kingdom.[1]
